This is the point that needs to be explained for Efferent vision to even be considered. Light travels at a finite speed, that everyone agrees on. But you claim that in Efferent vision the image of an object is at the eye without any time passing from the time the photons are at the object till the image (apparently photons) are at the retina. This point must be explained in a way that can be tested and proven. So to support Efferent vision, you need to come up with some testable hypothesis to do so. |
I said that if the object is large enough and bright enough (such as the example of the Sun being turned on), we would be able to see the Sun when it is first ignited for this very reason. In this account we are not receiving the image from the light itself, which would involve time; we are seeing the object because it is within our visual range and because it meets the requirements that would allow the object to be seen. |
You've stated multiple times that photons will be present at the eye when seeing the newly ignited Sun, but have refused to answer where the photons would come from or how they come to be present at the eye.
That is an irreconcilable contradiction. |
If the Sun were hot enough upon igniting, we would see it because the light resulting from fusion (bringing together 4 hydrogen nuclei to make helium) would create enough brightness that we could see it instantly, not 8 minutes later. Please don't answer this post because I don't want to get into this discussion again. |
LOL, weasel. I didn't ask about the brightness, I asked if there would be photons located at human eyes on Earth |
Tsk, tsk, LasyShea. Peacegirl said not to answer that post because she did not want to get into this discussion again. You are not very good at following directions are you?
